SATURATING ELEMENT FOR COOLING APPARATUS.

Specification of Letters Patent.

Application filed July 31, 1917. Serial No. 183,990.

To all vwhom t may concern.'

Be it known that I. CHARLES W. DAvis, a citizen of the United States, and a resident of the city of Sausalito, in the county of Marin and State of California, have invented a new and useful Improvement in Saturating Elements for Cooling Apparatus, of wh'ich the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to improvements in cooling devices wherein atmospheric heat is utilized to evaporate water thereby reducing the temperature of the atmosphere and has to do with the construction and arrangement of the water containing elements.

The reduction in atmospheric temperature in cooling devices of the type referred to is in direct proportion to the amount of water evaporated within a given period and similarly the amount of water evaporated is in direct proportion to the area of the exposed water. The present invention has for its object the exposure of a maximum water saturated area within a minimum air space' whereby a comparatively great saturated area is exposed to a 'comparatively small volume of air.

Another object of the present invention is to provide a saturated element adapted to convey the maximum amount of water or moisture to the exposed surfaces by capillary attractipn' by the employment of a pubescent container.

Anda further object is to provide an element having intersecting interior channels to convey water to substantially every portion of the element to provide the greatest possible saturation.

lt is also intended to provide a saturating means wherein the water pressure operating in conjunction with the attraction of gravity will cause a multiplicity of suspended particles or drops of water to be held within the air current to consume the heat from said current.

l accomplish these several objects by means of the preferred form of the device disclosed in the drawings forming a part of the present specification wherein like characters of reference are used to designate similar parts throughout thesaid specification and drawings, and in which- Figure l is a longitudinal sectional view of a cooling apparatus disclosing my improved atmosphere saturating devices applied thereto;

Fig. 6 is a sectional view taken on line G-IG ofA Fig. 5 in the direction indicated; anc

Fig. 7 is a sectional view taken through line 7 7 of Fig. 6. Y'

Referring to the drawings the numeral l is used ,to designate a housing having a water trough 2 in the upper portion thereof. Connected with and suspended from the Water trough 2 are several pipes 3 arranged in pairs and connected by means' of horizontally disposed perforated connections 4 the purpose of which will hereinafter be more fully described.

A second series of vertically disposed water pipes 6 are also arranged in pairs,

each pair being connected by several horizonta ydisposed perforated water pipes or connections 7.

Saturating elements or water containers 8, composed preferably of fabric or similar pubescent material, are strung between corresponding horizontal pipes 7 of the vertical pairs 6 and also suspended from the horizontal perforated pipes 4, each alternate pipe 4 being suspended at a slightly lower level than the remaining pipes in vorder to provide a tortuous channel 16 between the mats or elements 8 and extending throughout the .length ofthe housing 1. That is, some of the pipes 4 are suspended at an elevation which will suspend their respective mats or' elements 8 with their lower ends adjacent the bottom of the housing l and with the top ends of said mats or elements 8 spaced apart from the upperportion of said housing l.

The corresponding horizontally disposed pipes'? are arranged to slightly incline the elements8 when strung thereon the purpose of which will be more fully described.

Each-mat o r element 8 is tufted at regular intervals as at 9 to reduce the'capaclty of said element as a container so that at no time will an excessive amountof water bestored therein and'also to providey intersecting channels 10 by means of which; water from theperforated pipes 4 and 7 may be conveyed to substantially every portion of the interior of said elements 8 from whence said water or moisture is conveyed by capillary attraction, owing to the pubescent nature of the elementsS, to the outer surface of the mats.

' plurality of suspended drops or particles of ln the case of the .slightly inclined 'mats it isevident that the static pressure operat ,ing in conjunction with the capillary attraction induced by the pubescent nature of vthe mats 8 will c'ailse the lower side thereof to'be super-saturated and thereby produce a water hung directly within the path of an air current to remove a portion of the-heat from said current by the vvaporization process.

To provide the necessary current of air the housing 1 is providedat each end thereof with suitable ports 11 within which are mounted. suitable fans or blowers 12.-

The air current may be in either direction.: As the stationary moisture elements or mats 8 have their interiors directly connected to the perforated portions of the are' directly exposed to said draft vwhich during itspassage through the *channel 16l heat in eva'pov rating the water thereby lowering the temin the well known,y

will give up a portion'of its perature of theair current manner.

rlhe foregoing description is of stationary elements within a housing exposed to a conlng a hollow fa the lower end of a vertically disposed hollow armature shaft 19 of a well known type of ,ceiling fan.

`The armature 2 0 is secured to or mounted upon the hollow amature 'shaft 18 and is 'rotatably held in connection with the male member of stung gland 21 of a ceiling standard 22 bythe female member 23A secured to the field magnet housing 24.

Water is conveyed through the ceiling 4standard 22 to thehollow armature shaft 19and to the perforated pipes 17 and the' interior of themats or moisture laden elements 8.-

As the blades are rotated through the atmosphere an air current is created relatively to the fan blades and the mats 8 thereof.

rlhe speed of the blades should be insuilicient to create a degree of centrifugal force which will cause the moisture to be thrown oil from the -ends Aof the fan blades.

As the blades rotate the resulting air currents will evaporate the moisture on the surfaces ofthe mats 8l and the heat consumed by such evaporation will cause a lowering of the temperature of said air currents.

l am aware that the present state of artdiscloses devices for removingheat from the atmosphere by the evaporation of water. I therefore do n ot claim such a device broadly but What I claim as new and desire to secure by. Letters Patent -is y g 1. A device for lowering atmospheric temperature by `evaporation of water compris ing afabric element having a series of channels to convey water to lsubstantially all I partsA of said element.
